“…Researchers exploring strategies to manage white rot disease consider both efficacy and environmental implications, with traditional fungicides serving as a reliable but not always eco-friendly solution [6]. Among the alternatives are nanoparticles and chemical inducers, such as salicylic acid, which have demonstrated promising results in managing plant diseases [7,8].…”

This study investigated the effectiveness of nanoparticles and chemical inducers in managing onion white rot caused by Sclerotium cepivorum. The pathogen severely threatens onion cultivation, resulting in significant yield losses and economic setbacks. Traditional fungicides, though effective, raise environmental concerns, prompting a shift toward eco-friendly alternatives. In this study, four S. cepivorum isolates were utilized, each exhibiting varying degrees of pathogenicity, with the third isolate from Abu-Hamad demonstrating the highest potency. During the in vitro studies, three nanoparticles (NPs) were investigated, including Fe3O4 NPs, Cu NPs, and ZnO NPs, which demonstrated the potential to inhibit mycelial growth, with salicylic acid and Fe3O4 NPs exhibiting synergistic effects. In vivo, these nanoparticles reduced the disease incidence and severity, with Fe3O4 NPs at 1000–1400 ppm resulting in 65.0–80.0% incidence and 80.0–90.0% severity. ZnO NPs had the most positive impact on the chlorophyll content, while Cu NPs had minimal effects. At 1000 ppm, Fe3O4 NPs had variable effects on the phenolic compounds (total: 6.28, free: 4.81, related: 2.59), while ZnO NPs caused minor fluctuations (total: 3.60, free: 1.82, related: 1.73). For the chemical inducers, salicylic acid reduced the disease (10.0% incidence, 25.0% to 10.0% severity) and promoted growth, and it elevated the chlorophyll values and enhanced the phenolic compounds in infected onions. Potassium phosphate dibasic (PDP) had mixed effects, and ascorbic acid showed limited efficacy toward disease reduction. However, PDP at 1400 ppm and ascorbic acid at 1000 ppm elevated the chlorophyll values and enhanced the phenolic compounds. Furthermore, this study extended to traditional fungicides, highlighting their inhibitory effects on S. cepivorum. This research provides a comprehensive comparative analysis of these approaches, emphasizing their potential in eco-friendly onion white rot management.

Alternaria early blight is an air-borne and soil-borne pathogen that cause losses and damages that can reach up to 80% in tomato production. In our work, the immediate antagonistic effect of Bacillus pseudomycoides was inspected against Alternaria early blight of tomato. Bacillus pseudomycoides (Bp1) (OQ629426) gave inhibition efficacy against A. solani growth, being, 74.22 %. Invitro, Bp1 had the capability to produce the endogenous plant auxin (IAA) it was 18.9 (µg/100 mL), the quantity of GA 9.4 (µg/100 mL), 95.8 μ Deferroxamine mesylate. Tomato plants treated with B. pseudomycoides registered the least disease severity, being 50 and 40 % in Mancozeb + ALS and Bp1+ ALS treatments with high efficiency to control the severity between 75 and 100 % respectively. Tomato plants treated with B. pseudomycoides showed improved growth characteristics as compared with the untreated control. Plants with bacterial treatment conferred 45.6 cm shoot length, 2.9 (g∕plant) fresh weight and 0.7 (g∕plant) Dry weight. The highest increase in the activity of polyphenol oxidase (PPO) and peroxidase (POD) was observed in the infected leaves of tomato plants treated with B. pseudomycoides Bp1 (T4) (4.6, 6.9 m/g f. w.) respectively, followed by treatment of plants with Mancozeb (T3) (3.9, 5.4 m/g f. w.) respectively, compared to other treatments. This study suggested that B. pseudomycoides is a promising biocontrol agent against Alternaria early blight. This bacterium may represent an important source of potential antimicrobial bio-agent against Alternaria early blight disease, also it may play a role in the development of integrated control programs in future studies.
